Reduction Mechanism. Draw the major product for the reduction reaction below in the box. Then, draw the proper FULL electron-pushing mechanism for the reaction, including ALL intermediates (with formal charges) and electron pushing arrows. Label the Electrophile and Nucleophile in each step.
Reduction of Aldehydes:
Aldehydes will undergo reduction reaction using a reducing agent to produce primary alcohols. Sodium borohydride is an example of a reducing agent that can be used to reduce aldehydes to primary alcohols.
Answer and Explanation:
The product of the reaction reaction is given below.
The mechanism of the reduction reaction is given below.
Step 1: A hydride from the sodium borohydride does a nucleophilic attack on the carbonyl carbon of the aldehyde to generate a tetrahedral intermediate.
Step 2: Protonation of the tetrahedral intermediate gives the primary alcohol.
